Questions: Any Topic, Any Difficulty

LearnClash lets you search for any topic and play right away with questions matched to your skill level. Type “quantum entanglement,” “Renaissance art,” or “Australian wildlife” and get accurate questions at easy, medium, and hard difficulty. Each question goes through automated validation before it appears in duels or practice.

When we built the question system, we optimized for two things: topic coverage and difficulty calibration. The ELO rating system ensures you face questions at your level. A player rated 1400 sees harder questions than one rated 800 on the same topic. That keeps it fun for beginners and experts alike.

Trivia Crack relies on a community-submitted question pool across six categories: Science, Entertainment, Art, Geography, Sports, and History. The database is large but finite. Play long enough and you’ll hit repeat questions. Niche topics like paleontology, crypto, or K-pop history simply aren’t there.

In our experience, the hardest part wasn’t making questions. It was validating them. LearnClash runs each question through automated fact-checking before it enters the pool. Wrong or unclear questions get filtered out. That’s why accuracy stays high even on obscure topics.

Did you know? LearnClash covers topics as specific as “dinosaur paleontology” or “Mars exploration,” topics that would never appear in a fixed-category quiz app. For a sample, try our 43 general knowledge questions, 37 science trivia questions, 37 Lord of the Rings trivia questions, or 37 Harry Potter trivia questions. Winner: LearnClash. Infinite topics at every difficulty level beats a static question pool limited to six categories.

Multiplayer: 18-Question Duels vs Random Wheel Spins

LearnClash structures each duel as 6 rounds of 3 questions each, 18 questions total across 6 different topics. The algorithm ensures all 6 topics are distinct. A single duel might cover history, astronomy, cooking, sports, music, and biology. Breadth wins here. Each duel has a 48-hour window, so you can play at your own pace.

LearnClash duel with 18 questions across 6 topic groups (history, science, cooking, sports, music, art) and 48h timer vs Trivia Crack spinning wheel with 6 fixed categories and crown icons LearnClash structures duels as 18 questions across 6 diverse topics, while Trivia Crack uses a random wheel spin to select categories.

Variety6 semantically different topics per duelRandom from 6 fixed categories
TimingAsynchronous (48h window)Asynchronous (turn-based)
OutcomeSkill-based (diverse knowledge wins)Luck-dependent (wheel determines category)

When we tested duel formats during development, the 6-topic structure hit the sweet spot. It’s diverse enough to prevent one-trick players from dominating, but focused enough per round (3 questions per topic) to truly test knowledge. LearnClash also supports topic-locked duels where all 18 questions focus on a single topic. Perfect for deep-dive challenges with friends.

Trivia Crack uses a wheel-spin mechanic that randomly picks which of the six categories you’ll answer. This adds a gambling element: a history expert might land on Sports three times in a row. Games stretch over hours or days. The random category pick means the outcome often depends on luck, not knowledge.

Winner: LearnClash. 18 questions across 6 varied topics creates a fairer, more competitive experience than random wheel spins.

Ranking: ELO Ratings vs Crown Collection

LearnClash uses an ELO rating system inspired by competitive chess to rank players by actual skill. New players start at an ELO of 800 with a K-factor of 40. Early matches produce large rating swings that quickly find your true level. After 10 duels, the K-factor drops to 20 for smaller, more stable shifts. Ranks progress through 8 tiers: Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, and Phoenix. See our full ELO rating system breakdown for the exact math and worked examples.

When we analyzed matchmaking data, ELO-matched players produced far more balanced duels than random pairing. The system ranks open duels by ELO proximity and category/topic overlap, favoring opponents at a similar skill level who share your interests.

“The rating of a chess player is a number which may be used as an index of his proficiency. Its purpose is to provide a fair method of handicapping.” — Arpad Elo, The Rating of Chessplayers, Past and Present (1978)

Infographic comparing LearnClash ELO tier system with 8 tiers from Iron to Phoenix (2400+), starting at ELO 800 (Bronze) versus Trivia Crack crown collection mechanic (collect all 6 category crowns to win) LearnClash ranks players by skill using 8 ELO tiers, while Trivia Crack uses crown collection with no skill measurement.

LearnClashTrivia Crack
SystemELO rating (800 start)Crown collection
PersistencePermanent, cumulativePer-game crowns
Tiers8 (Iron → Phoenix)None
MatchmakingELO-balanced opponentsRandom

Trivia Crack uses a crown collection system. Win games to earn crowns in each of the six categories. Collect all six to win. Simple and satisfying, but it tells you nothing about skill. A player who wins 10 easy games looks the same as one who wins 10 hard ones. No tiers, no skill-based leaderboard, no matchmaking.

This matters because ELO creates a loop that keeps you coming back. Every duel counts. A win against a higher-rated player earns more points than a win against someone below you. Climbing from Iron to Phoenix is a real achievement that reflects genuine knowledge growth.

Winner: LearnClash. ELO provides meaningful, skill-based progression that adapts to your actual knowledge level.

Learning Value: Spaced Repetition Everywhere vs None

LearnClash builds lasting knowledge through spaced repetition that works across every game mode, not just practice. Any question you see in a duel or practice session enters the spaced repetition cycle. Questions repeat at growing intervals (7 days, 90 days) until you’ve mastered them. Even casual duel play builds real knowledge over time.

We built spaced repetition into the core of LearnClash because testing effect research shows retrieval-based study doubles long-term retention versus rereading. The results are clear. The dedicated practice mode gives you an extra edge: 9-question solo sessions on any topic, tracking your knowledge across three mastery levels: Learning, Known, and Mastered.

“The spacing effect is one of the most robust findings in experimental psychology.” — Cepeda et al., Psychological Bulletin (2006)

Knowledge retentionCompounds over timeNo retention mechanism

Trivia Crack has no spaced repetition, no mastery tracking, and no way to study specific topics. It’s pure fun. You play, you answer, you move on. There’s no way to revisit questions you got wrong or build knowledge step by step.

The gap shows up fast. After a week of LearnClash, you’ll have moved dozens of questions from “Learning” to “Mastered” with real retention, even from regular duel play. After a week of Trivia Crack, the forgetting curve erases most of what you saw.

Did you know? LearnClash’s SRS algorithm adjusts review timing after every answer. A question you miss drops one mastery stage and appears again soon, while a mastered question exits the review pool entirely. Winner: LearnClash. Spaced repetition across all game modes builds permanent knowledge, not just temporary fun.

Pricing and Ads: Ad-Free vs Ad-Supported

LearnClash is fully ad-free on every tier, including the free plan. No banners. No interstitials. No rewarded video ads. Zero ads. The free tier includes unlimited duels, all topics, ELO rankings, and full spaced repetition. Premium ($7.99/month or $59.99/year with a 7-day free trial) adds per-topic stats, streak freezes, and exclusive cosmetic rewards.

LearnClash free tier includes all features with zero ads vs Trivia Crack free tier with unskippable video ads; LearnClash Premium $7.99/mo or $59.99/yr vs Trivia Crack ad removal $3.99/mo LearnClash is ad-free even on the free tier, while Trivia Crack’s free tier includes unskippable video ads between rounds.

Paid price$7.99/mo, $59.99/yr$3.99/mo (ad removal)
Paid featuresStats, streak freeze, cosmeticsAd-free play

Trivia Crack runs unskippable video ads between rounds on the free tier. The ads break gameplay flow and add 15-30 seconds of waiting per game. The paid tier ($3.99/month) removes ads but adds no study tools, stats, or ranking features.

When we compared the two pricing models, the gap was stark. LearnClash’s free tier offers more features than Trivia Crack’s paid tier. You get ELO rankings, spaced repetition, all topics, and zero ads without spending a cent.

Winner: LearnClash. Zero ads on the free tier, and premium adds genuine learning features rather than just removing advertisements.

Daily Engagement: Quests, Streaks, and AI Tutor

LearnClash keeps you coming back daily with features built around learning, not just habit loops. Daily quests give you specific goals (win 3 duels, master 5 questions in practice) that reward experience points and climb the quest chain. Friend quests let you team up toward shared goals.

LearnClash daily engagement: daily quests, friend quests, streak freeze, AI tutor Clash vs Trivia Crack with weekly challenges only and no quests, streaks, or AI tutor LearnClash offers daily quests, cooperative friend quests, streak protection, and an AI tutor, while Trivia Crack has weekly challenges only.

Streaks track days played in a row. Miss a day? LearnClash Premium includes a streak freeze that protects your chain. The AI tutor mascot Clash explains wrong answers, chats about any topic, and makes studying feel like a conversation, not a flashcard grind.

Trivia Crack offers weekly challenges but has no daily quest system, no cooperative friend quests, no streak protection, and no AI tutor. Play, spin, collect crowns, repeat.

Winner: LearnClash. Daily quests, friend quests, streak protection, and an AI tutor create a richer engagement loop than weekly challenges alone.
